Epiphyllum anguliger, scientifically identified as an epiphytic cactus native to the tropical evergreen forests of Mexico, is commonly known as the Dream Catcher Plant. It is also called the Fishbone Cactus or Zig-Zag Cactus due to its uniquely shaped foliage. The plant features flattened, succulent stems that grow in a striking, deeply serrated, angular pattern resembling a fish skeleton. Unlike the desert cacti often encountered, this species originates from a humid jungle environment, which dictates a specialized approach to its cultivation.
Essential Environmental Requirements
The plant thrives best in bright, indirect light throughout the day, mimicking its natural habit beneath a forest canopy. Placing it near an east or west-facing window, or a filtered south-facing window, usually provides the ideal light intensity. Direct, harsh midday sunlight should be avoided, as this exposure can easily scorch or bleach the green stems.
As a tropical species, Epiphyllum anguliger prefers consistent warmth. The optimal temperature range for active growth is between 65°F and 80°F (18°C and 27°C). It is sensitive to cold and should never be exposed to temperatures falling below 50°F (10°C). Maintaining a higher level of ambient humidity, often found in kitchens or bathrooms, will also support its growth.
Soil and Repotting Practices
As an epiphyte, the Dream Catcher Plant naturally grows on other trees, meaning its roots require exceptional aeration and drainage. Standard potting soil is too heavy and will compact quickly, leading to retained moisture and eventual root problems. The ideal substrate is a chunky, fast-draining mix designed to prevent the roots from sitting in saturated conditions. A suitable blend can be created using a mixture of orchid bark, coarse perlite, and a small amount of cactus or succulent potting mix.
This plant prefers to be somewhat pot-bound and does not require frequent repotting. Repotting is best done in the spring, typically only every two to three years, to refresh the substrate and allow for a slight increase in pot size. Only move it to a larger container once the roots are visibly emerging from the drainage holes or the plant’s growth seems restricted.
Routine Maintenance: Watering and Fertilizing
Watering
During the active growing period of spring and summer, the plant should be thoroughly watered using the “soak and dry” method. This involves soaking the entire pot until water runs from the drainage holes. Then, allow the top half of the soil mix to dry out completely before watering again. Always use tepid water for irrigation, as cold water can shock the root system and inhibit nutrient uptake.
Dormancy
Watering frequency must be significantly reduced during the fall and winter months when the plant enters a period of semi-dormancy. Over this cooler period, the plant requires only enough moisture to prevent the succulent stems from shriveling. Water only once the entire potting medium has dried out completely.
Fertilizing
To support vigorous growth during spring and summer, a diluted liquid fertilizer should be applied every two to four weeks. Use a balanced houseplant formula or one that is slightly lower in nitrogen, as excessive nitrogen can encourage soft growth. The fertilizer should be diluted to half or even quarter strength to prevent chemical burn, as epiphytes are accustomed to low-nutrient environments. Fertilizing must be discontinued completely during the late fall and winter rest period.
Propagation and Addressing Common Issues
Propagation
Propagating Dream Catcher Plants is easily accomplished through simple stem cuttings. Select a healthy stem segment that is at least four to six inches long and use a clean, sharp blade to make the cut. The cut end must be left exposed to the air for several days until a dry, protective layer, or callus, forms over the wound. This callousing process prevents the cutting from absorbing too much water and rotting upon planting. Once the cut surface is fully dry, the segment can be planted vertically into the recommended well-draining, chunky soil mix. Keep the soil slightly moist, but not wet, until new roots begin to establish, which often takes several weeks.
Common Issues
The most common cultivation problem is root rot, which is almost always caused by overwatering or using an insufficiently draining soil mix. Should this occur, the affected roots must be trimmed away, and the plant repotted into a fresh, drier medium. Pests like mealybugs and scale insects may occasionally appear on the stems. These can be treated by gently wiping them away with a cotton swab dipped in isopropyl alcohol or applying a light coating of horticultural neem oil.
